Device for inducing noise signal on the power supply network NS-111

The NS-111 device contains a power supply unit and a noise voltage induction circuit in the power supply and grounding circuits.

The device converts noise voltages coming from the GS via channel "B", and the generated noise signal is transmitted via a matched 50 Ohm cable through a network plug in the power supply and grounding lines for the "phase" - "ground" and "zero" - "ground" circuits.

The module is equipped with barrier filters that prevent the induced noise signal from penetrating into the noise generator's own power supply circuits with protection against equivalent short circuit (inductive load).

Technical specifications:
Module dimensions 120x60x40 mm

The "Chiffon" system is designed to protect information processed by technical means at information technology facilities by emitting an electromagnetic field of masking noise into the surrounding space and generating electrical masking noise signals in power supply and grounding lines extending beyond the controlled area.

"Chiffon" can be an element of the general information protection system of information technology facilities and ensures, in unattended operation mode, masking of the following signals that form channels for possible information leakage via PEMIN:
By type "A" - informative side electromagnetic radiation from technical means and their communications processing classified information at information technology facilities and interference from PEMI to other technical means located at the information technology facility and their communications extending beyond the controlled area.
By type "B" - induction of radiation from technical means into an electrical signal along grounding and power supply circuits extending beyond the controlled area of ​​the information technology facility.

The Chiffon security system includes a noise generator (NG) and terminal emitters of noise signals (IE) connected to it via connectors.

The Chiffon security system can be manufactured in three design variants:

The basic version is a masking radio noise master generator with a control and indication system keyboard, a power supply module and a guidance device (design variant - GS-111) housed in a single metal case.

If an external power source and a guidance device are used, the central generator unit can be made in a plastic case (design variant - GS-111P).
When controlling the generator remotely from a PC (using the Shlyuz security system software), the control panel on the generator may not be installed (design variant - GS-111U).

The following can be used as the final emitters of the noise signal:
1) The TA-111 pin telescopic antenna.
2) The PA-111 flat electromagnetic antenna.
3) The MA loop magnetic antenna (if necessary).
4) The NS-111 power supply network signal guidance device.

Functional characteristics of the "Chiffon" system:
•A "Gaussian" noise generator with a continuous (uninterrupted) spectrum in the operating frequency band of 0.01 - 3000 MHz with a multi-band frequency equalizer and digital output level adjustment separately for each sub-range of at least 30 dB is used as the noise source.
• The ability to connect via an Ethernet network allows you to combine the information protection system of any object into a single IP network to form a distributed information protection system for monitoring and control from one operator station using specialized software of the "Gateway" USZI.
• Monitoring and indication of normal operation or occurrence of an emergency (visual, audio, text) allow receiving information about the system operation in real time on the control panel of the generator unit or personal computer monitor.
• Automatic continuous self-diagnostics of system components.
• Automatic monitoring of the levels of the electromagnetic field generated by the ISH through a separate antenna input.
• Integrated counter of the system operating time in the interference generation mode with data storage in non-volatile memory.
• Saving settings in non-volatile memory. Detection and protection from unauthorized access to system settings (digital password).
• Operation in unattended round-the-clock mode.
• Power supply of the systems is 220 V 50 Hz network or through a backup DC source 12 V/1.5 A.

The system is certified by the FSB and FSTEC of Russia for compliance with information security requirements.
The system is certified by Rosstandart for compliance with the requirements of the Customs Union for electrical fire safety and electromagnetic compatibility. The system has an expert opinion on compliance with sanitary and hygienic standards defined by the "Unified Sanitary and Epidemiological Requirements for Goods Subject to Sanitary and Epidemiological Supervision (Control)" of the Customs Union.
